When Sukkot falls on Thursday and Friday, an Eruv Tavshilin must be made in order to be able to prepare for Shabbat on Friday. On Wednesday afternoon one sets aside one baked and one cooked item; usually an egg or fish and a challah are used. These eruv foods are held while the following blessing and declaration are recited and are then left in a safe place. They may be eaten on Shabbat.
BLESSING :
Baruch ata Ado-noi Elo-heinu melech ha-olam, Asher kidi-shanu b’-mitzvo-tav, V’-tzi-vanu al mitzvat eiruv.
Blessed are You, the Lord our God, King of the universe, Who sanctified us with His commandments, and commanded us in the mitzvah of eiruv.
DECLARATION:
Through this eruv may we be permitted to bake, cook, keep foods warm, light candles, prepare and do anything necessary on the Festival for the sake of the Sabbath .
